The Lowdown

Alright, this is Rusty comin' at ya with the outlook for Jaconé.

First up, the water temp is sittin’ at about 72°, which is pretty average for this time of year. No crazy anomalies to worry about.

We’ve got a bit of a slow start, but the action starts pickin’ up from Thursday morning the 27th. It’s not for the faint of heart though – we’re lookin’ at a solid 8 ft S swell with a long 14-second period. That’s a powerful groundswell, with combined energy of 2407, so there’s plenty of punch. It’s gonna be a clean one with light cross-offshore winds, but this is strictly for the experienced crew. That size is in the expert zone. Thursday afternoon holds similar, with a 8 ft SSE swell, still clean and offshore.

Friday the 28th sees the swell drop back a bit. Morning brings 4 ft S swell, still with that nice offshore wind, so it’ll be clean. The energy is moderate at 642. Afternoon gets a bit smaller and the wind picks up, making it more marginal.

Saturday the 29th is a small day. Morning has a tiny 2 ft S swell with a light offshore – just small and clean for a longboard or a learner. Afternoon picks up a bit to 3 ft but it’s a short-period E windswell, so not much to get excited about.

Now, Sunday the 30th and Monday the 31st are where it gets interesting for the intermediate crew. Sunday morning we get a 7 ft ENE swell with an 8-second period and light offshore wind. Clean, punchy, good energy at 746. Monday morning is even better, with a similar 7 ft ENE pulse, also clean and offshore. These will be fun, powerful waves but not too unruly. The consistent offshore wind is a major positive.

Tuesday the 1st of September things turn ugly with onshore winds and poor conditions – a write-off.

Wednesday the 2nd brings a big pulse, but it’s tricky. Morning has a 7 ft SSW swell but with onshore wind and a thumping 1176 energy. Afternoon is where it gets wild: a 10 ft SSW swell with a 12-second period and 2392 energy. The file says it’s predicted to be too big for this break, so unless you’re a gun looking for a challenge and the tide is right, steer clear. The cross-onshore wind won’t help.

Thursday the 3rd is a standout for the experienced crowd again. We’ve got a 8 ft SSW swell in the morning and 8 ft S in the afternoon, both with clean cross-offshore winds and solid 11-second periods. Energy is strong at around 1350-1400. This is excellent, powerful surf for those who can handle it.

Friday the 4th is still solid, with 6 ft and 5 ft S swell, clean with moderate offshore winds. Good energy in the 500-630 range. A solid option for strong intermediates and above.

Saturday the 5th sees the swell drop to around 4 ft with a nice SSE direction, but the wind is a fresh 30 km/h offshore in the morning. It’ll be clean but blustery.

Sunday the 6th, the morning is a bit messy with light cross-on wind, but the afternoon is a beauty. A clean 5 ft S swell with a very long 13-second period, almost no wind, and 962 energy. That’s a glassy afternoon session with a lot of grunt. The long period means it’ll be better shaped at the point or reef setups.

The following week from Monday the 7th into the 11th has a few more windows. The best of the bunch looks like Friday the 11th: a clean 6 ft SSW swell with a long 13-second period, gentle offshore wind, and energy over 1100. That’s a top-shelf day for experienced surfers.

So, the true standouts in this run are Thursday the 3rd September for the big, clean S/SSW swell, and Friday the 11th September for that long-period SSW groundswell with perfect offshore conditions. Those are the days to circle on the calendar.

For the rest, there are plenty of clean windows with offshore winds, but the size and quality fluctuate. The consistent offshore wind pattern here is a real treat.

Stay stoked, check the buoys, and I’ll see you in the water.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
